I just started loading about a month ago and was pretty nervous at first. One book that really helped me was the "Modern Reloading" 2nd edition by Richard Lee. The book kinda leans towards Lee Reloading equipment (go figure), but is very helpful. It also has a lot of reloading data for many calibers. One load I'm having trouble looking for though is for a .300rum with a 175 grain bullet (berger). If anyone has any info for this round, I'd really appreciate it.
